The 1993 Illinois High School Association (IHSA) State Championship Tournaments ended the seventh State Championship Series conducted in Scholastic Bowl by the IHSA. It was the second season in which there were separate State Championship Tournaments held for small schools (Class A) and large schools (Class AA).
1992 marked the first time where small schools and large schools would be separated and compete for different State Titles. While the process for determining the cutoff for determining classification has changed over time, it has roughly hovered around the 725-750 student area. Thus, about 30-40% of the schools would compete as Class AA, and 60-70% of the schools would compete as Class A. This permits a roughly equal number of students to compete in each class.
In each class, the state was divided into 16 areas, termed in Illinois as Sectionals. Each sectional hosted a tournament, the winner of which advanced to the State Championship Tournament. The determination of these geographic boundaries was arbitrarily decided by the IHSA Office.
Each round was comprised of 30 toss-ups and accompanying bonus questions. The sectional tournaments and State Championship Tournament were all single elimination. Teams were randomly assigned to positions in the bracket without regard for record or performance.
The exception to the single elimination format occurred in the semifinals, where the two semifinal losers played a third place match. The top four teams earned trophies and medals for team members, coaches, principals, and activities directors. The trophies were of the design smaller than that of the athletic trophies given out by the IHSA.
The Class A State Championship Tournament was held at Rochester Elementary School. This would be the second and final year that the State Championship Tournament would be held at this site.
One Sectional Champion did not attend this tournament. St. Bede High School was thus given a bye to the quarterfinals.
The Class AA State Championship Tournament was held at Lanphier High School in Springfield. This was the third and final year that Lanphier hosted the State Championship Tournament.
One team failed to appear to compete. Homewood-Flossmoor was thus in the random position to earn a bye and begin competition in the quarterfinals.
- This was Quincy's third and final State Championship under their legendary coach, Beth Young.

- Prospect's 74 points is the Class AA record for the fewest points scored in a State Championship Tournament match.
